We’ve thought about going on one of the many “behind the scenes” tours available at the different Walt Disney World parks, and finally today we went on the “Keys To The Kingdom” tour, about 4-1/2 hours in the Magic Kingdom, including lunch, and including a couple of trips beyond the public area – down behind Splash Mountain and Pirates of the Caribbean (where the parade floats are), under the park in the famous Utilidors, and behind Main St (where there wasn’t much to see except an escaping Cinderella!)
Officially, you can’t take pictures “back stage”, but …

Seems you should be giving the tour… 😉
Is there a Club 33 at this Disneyland?
No. Not heard of it but just Googled … Never keen on restaurant with “dress code”; they want to be comfortable but they don’t care if I am not.
My brother n law belongs and takes clients there.
